R/proc_trendecon.R
proc_trendecon.RdInternal worker behind proc_trendecon_ch(), proc_trendecon_de() and
proc_trendecon_at(). Each index is processed in isolation: if one index
(or a keyword within it) fails, the remaining indices still run, and every
index that succeeds is copied to data/<geo> immediately. This prevents a
single bad keyword or a transient Google Trends error from zeroing out the
entire daily run.
proc_trendecon(geo, indices, backfill_from = NULL)Two-letter geography, e.g. "CH".
Named list mapping each index name to its keyword vector. Indices are processed in list order.
Optional start date (YYYY-mm-dd) passed to
proc_index() / proc_keyword_backfill_daily() to fill a daily gap left by
an outage. Use once; leave NULL for normal daily runs.
Invisibly, a data frame with one row per index and columns
geo, index, ok, error. Stops with an error only if every index
failed.
